NFL running backs have such a short shelf life, that the league is always looking for another. He's got some appeal with his size and ability to get a yard, catch the ball out of the backfield and potentially learn the fullback position (though he's not a fullback right now, not even close)
Next year is a rebuilding season for the Cougs and Harvey will be the focus of the opposing defense, daring whoever we throw in the mix at QB to throw the ball.
The bright side, is that Harv would also me the most reliable weapon we have and could rush for 2000 yards (if used correctly) with the returning offensive line we have.
Whatever he decides, I wish him well. He's been in the mix at BYU for a lot of wins and never spoken up or complained when a lot of us believe that he should have gotten the ball a lot more.
If he does actually decide to return, I'll be the 1st to go out and buy his '84 throwback jersey and I'll put him firmly on my top 5 fav Cougar list for doing such; but I wouldn't blame him for leaving.
Brian Kariya, JJ Dliuigi, and even Drew Philips will be a nice change of pace.... but I liked having that beef in the backfield on pass protection.
